I talked at length with the owner of The Jig Stop (bait and tackle shop) here in Dana Point. He has over 50 years of experience fishing the exact spot I was at. He doesn't think it was a White Seabass, Black Seabass, or a Bat-Ray, but a large Sheepshead as he has landed (and lost) many here over the years. I think I would have had a real shot at that fish too if I had a live bait hook (stronger) and a more buttoned down drag!? Lessons learned for next time!!!
